The Crown Jewels of the United Kingdom, originally the Crown Jewels of England, are a collection of royal ceremonial objects kept in the Jewel House at the Tower of London, which include the coronation regalia and vestments worn by British monarchs.

The Jewel House is a vault housing the British Crown Jewels in the Waterloo Block at the Tower of London. It was opened by Queen Elizabeth II in 1994 and refurbished in 2012. Regalia have been kept in various parts of the Tower since the 14th century after a series of successful and attempted thefts at Westminster Abbey.
